Abstract: The bearing devices includes a pair of opposed sidewalls, a supporting shaft which is inserted into shaft end insertion holes provided in the both opposed sidewalls, and a roller supported between the both opposed sidewalls by the supporting shaft. The supporting shaft includes a shaft main body that is made of a steel product subjected to a heating process and has a step shape in which the outer diameters of the both shaft ends are smaller than that of a middle portion and caps which is fitted to the both shaft ends and of which the end can be caulked. An end outer-diameter side edge of the cap is caulked to an inner-diameter side edge of the insertion hole.

Abstract: A rocker arm bearing comprising a support shaft in which end faces of shaft end portions of the support shaft are crimped to inner circumferential edges of shaft end inserting holes in opposed side walls and an outer ring which is rotatably supported on a raceway portion at a shaft intermediate portion of the support shaft via a plurality of rollers or directly, wherein an external surface of the raceway portion at the shaft intermediate portion of the support shaft is surface hardened by virtue of quenching, and as a wear-resistant hard coating, a DLC coating is formed on at least the external surface of the raceway portion which is surface hardened.
